In my opinion - it’s just a shame that the USSR had rifles with the smallest magazines of all automatic rifles. Moreover, the existence of such magazines has long been confirmed in reality. If it was justified before the FG damage buff, it is no longer justified after it. is that it was necessary for balance. People had been asking for this for over a year. There are probably more than 15-20 posts on the Russian forum about stores for 20 AVT-40s. Not to mention that the USSR is about to fight Japan, and the Type Hei automatic rifle has a 30-round magazine. 15 versus 30, it’s not even funny. This is truly a great victory for the Soviet faction, and I congratulate them on it.
By the way, there is a 20-round magazine of the KB-180 design in the game. Let’s talk about it in a little more detail.

In November 1942, by personal order of Stalin, Tokarev and the design bureaus OKB-16 and OKB 180 were tasked with manufacturing a 20-round magazine. Field tests of the magazines were conducted, with the 20-round magazine from KB-180 showing the best results. After the tests, it was planned to manufacture 3,000 rifles with the KB-180 magazine by the end of 1942. Thus, work was underway at Plant No. 314 to develop the new magazine, and in January 1942, a trial batch of 1,500 rifles with increased-capacity magazines was produced. By June 1943, a total of 11,425 such rifles had been manufactured. Rifles with 20-round magazines were sent to Central Arsenal No. 36, and by August 1943, there were 18,500 AVT rifles with 20-round magazines there. In total, more than 18,000 20-round magazines were produced for the KB-180.
Unfortunately, the future fate of the 20-round magazine leaves much to be desired.
As a result, the GAU decided not to issue the AVT with 20-round magazines to the troops and to return them to the factory to be replaced with 10-round magazines. It was decided to leave 200 rifles with 20-round magazines that had passed inspection at TsABV No. 36 and keep them in storage.
However, at least most likely the SVT with a 20-round magazine was at the front and participated in the war.
And besides, if we recall the Type Hey automatic rifle, which remained a prototype, with only a couple of units ever made and no participation in the war whatsoever, then… It’s not critical.
Special thanks to the developers for deciding to add a more or less mass produce magazine rather than some kind of prototype.
